❓ What are SAP Calculations?

SAP stands for Standard Assessment Procedure. It’s the government-approved method for evaluating the energy performance and carbon emissions of residential buildings.

You’ll need SAP Calculations for:

• New build dwellings

• Conversions (e.g. a barn into a home)

• Extensions with large areas of glazing

• Some refurbishments where thermal elements are altered

SAP Calculations confirm your project complies with Part L of the Building Regulations, that focuses on energy efficiency and conservation. In addition, an EPC (Energy Performance Certificate) will be issued once the project is completed.
